Antagonismo LTD^ no íleo de Porquinhos da ÍndiaLTD ^ antagonism in guinea pig ileum

Segmentos frescos de ileo de porquinhos da Índia foram suspensos em banhos de tecido de 2 ml contendo solução de Tyrodes oxigenada modificada. Após um periodo de equilíbrio, foi gerada uma curva de resposta de dose agonista por exposição de cada tecido a 4 diferentes doses LTD^ e medindo as alturas contrãcteis seguintes. Os segmentos ileo foram lavados e repousaram entre as exposições ao agonista. Após isto, os tecidos foram incubados com uma só concentração do composto de teste e o processo da dose de resposta agonista foi repetido. A dose de ração é uma medida da capacidade do antagonista para mudar a curva da dose de resposta agonista para a direita. E derivada como a concentração do agonista necessário para atingir um dadao nível de resposta no (A')presente em comparação com o (A) ausente de antagonista. Por exemplo, se a concentração do composto de teste não tiver qualquer efeito na resposta agonista induzida (A’=A) a relação de doses aproximar-se-àFresh segments of guinea pig ileo were suspended in 2 ml tissue baths containing modified oxygenated Tyrodes solution. After an equilibrium period, an agonist dose response curve was generated by exposing each tissue to 4 different LTD4 doses and measuring the following contractile heights. The ileo segments were washed and rested between exposures to the agonist. After that, the tissues were incubated with a single concentration of the test compound and the agonist response dose process was repeated. The feed dose is a measure of the antagonist's ability to shift the agonist response dose curve to the right. It is derived as the concentration of the agonist needed to achieve a given level of response in the (A ') present compared to the (A) absent antagonist. For example, if the concentration of the test compound has no effect on the induced agonist response (A '= A) the dose ratio will approach

de 1. As relações de dose aumentam se o composto inibir a resposta agonista induzida. Um valor de relação de dose é determinado para cada tira de ileo usado para o teste antagonista. Se as relações de dose aumentarem como uma função do aumento da concentração antagonista, estes dados podem ser avaliados por análise Schild para detrminar se a inibição é competitiva e se for, qual é o valor pA2 para o composto. A análise Schild examina a linearidade da função descrita pelas relações de dose escrita como log (A'/A) em função da concentração antagonista. Se a linearidade é confirmada e a inclinação se aproxima de -1, a inibição é considerada como sendo competitiva. 0 pA2 é o log negativo da concentração antagonista necessária para produzir uma relação de dose de 2. Este valor é considerado como sendo uma medida da afinidade do antagonista competitivo.of 1. Dose ratios increase if the compound inhibits the induced agonist response. A dose ratio value is determined for each ileo strip used for the antagonist test. If dose ratios increase as a function of increasing antagonist concentration, these data can be assessed by Schild analysis to determine whether inhibition is competitive and if so, what is the pA 2 value for the compound. The Schild analysis examines the linearity of the function described by the dose relationship written as log (A '/ A) as a function of the antagonistic concentration. If linearity is confirmed and the slope approaches -1, the inhibition is considered to be competitive. PA 2 is the negative log of the antagonist concentration required to produce a dose ratio of 2. This value is considered to be a measure of the affinity of the competitive antagonist.

Este resultado foi a seguir dividido pela ligação especifica sem o composto e multiplicado por 100. Estes valores foram transformados logit e aplicamos a regressão linear sobre os dados da res-20-DETERMINATION OF IC 5Q VALUES: - The specific LTD 4 bond was determined as the difference between the 3H-LTD 4 bond alone and in the presence of unlabeled 1 mM LTD. The unspecified LTD4 bond was also removed from tubes containing the compound as well. The percent inhibition of binding for each dose of compound was calculated by subtracting the specific binding in the presence of compound for the specific LTD1 binding in the absence of compound. This result was then divided by the specific bond without the compound and multiplied by 100. These values were transformed logit and we applied the linear regression on the res-20-

ginando 0,447 pmol de receptor/mg de proteina. As concentrações de proteina nestes ensaios foram ajustadas para fornecer aproximadamente 0,1 nM de receptor na presença de H-LTD^ nM. A incubação foi efectuada durante 30 min. a 24°C e usamos métodos de filtração para separar o ligado do ligado livre. Nestas condições, os valores Ι05θ para LTD^ e FPL 55712, um antagonista de receptores de LTD» conhecido, foram 1,71xlO~M e 10,37xl0“°M respectivamente. Todos os compostos testados foram inicialmente solubi1izados em DMSO. Cada composto foi avaliado com uma dose de 10 uM (10 M) em triplicado em 2 ensaios separados. A percentagem de inibição da ligação especifica LTD^ para cada composto é apresentada na Tabela 3.Pelo critério estabelecido para os antagonistas de receptores LTD^ potenciais, os compostos são activos se a concentração de teste 10 uM inibe a ligação especifica LTD^ em 45% ou mais. Usando este parâmetro, todos os compostos da Tabela 3 foram considerados inactivos em relação ao FPL 55712 .yielding 0.447 pmol of receptor / mg of protein. Protein concentrations in these assays were adjusted to provide approximately 0.1 nM of receptor in the presence of H-LTD ^ nM. The incubation was carried out for 30 min. at 24 ° C and we use filtration methods to separate the bound from the free bound. Accordingly, the values for θ Ι0 5 LTDâ FPL 55712 and a receptor antagonist for LTD "Known were 1,71xlO ti ~ M 10,37xl0" ° F respectively. All compounds tested were initially solubilized in DMSO. Each compound was evaluated at a dose of 10 µM (10 M) in triplicate in 2 separate assays. The percentage inhibition of specific LTD LTD binding for each compound is shown in Table 3. By the criterion established for potential LTD LTD receptor antagonists, the compounds are active if the 10 µM test concentration inhibits the specific LTD4 binding by 45% or more. Using this parameter, all compounds in Table 3 were considered inactive with respect to FPL 55712.
